DESCRIPTION

The TSM1121 integrated circuit incorporates all

sensing circuitry to regulate and protect from over

voltage and under voltage a multiple output power

supply (3.3V, 5V and 12V).

TSM1121 incorporates all the necessary functions

for Housekeeping features which allow safe

operation in all conditions, and very high system

integration.

TSM1121 integrates a precise voltage reference.

APPLICATION

s

PC SMPS triple power line housekeeping ic

(3.3V 5V 12V)
